Add menu problems in the sync_blender_master branch

We have the sync_blender_master branch where we merge the newest changes from blender into Bforartists. So that we can keep the Bforartists master in a working stage. And to merge this changes at a later point into the Master when the next Blender version is ready.

Usually you get errors when something doesn't fit. The merge conflicts. But sometimes this merge makes nonsense without you notice it. And then later you stumble across it.
